3x² + 14x + 8
3x² + 12x + 2x + 8
3x(x) + 3x(4) + 2(x) + 2(4)
3x(x + 4) + 2(x + 4)
(3x + 2)(x + 4)
63 = 0.63×10² = 126/2 = 3×21 = √3969 = 77₈
The last is as a base-8 number.
The distace between the center of dilation and point a is diven by:

The distance between the center of dilation and point a' is given by:

It can be seen that the distance from the center of dilation to the image is 1/4 times the distance from the centre of dilation to the preimage.
Therefore, the scale factor is 1/4.
5/8
